id like to add that if you're welding on older vehicles without CANbus systems (digital) it's ok. But the vehicle has Canbus use a surge protector on the battery instead. It has to potential of burning out modules.

I have never used a flux core wire in any welding situation. Never heard of it, but a 125 Cu. Ft. Tank of 25/75 cost me $55.88 on my last purchase in July 2021. It has actually gone down in price as my folder has invoices back to 1984 when I got my 150 amp MIG welder. It is tough to weld exhaust pipe period. You have tons of contaminants, aluminized pipe that varies from cheap electro-plating to hot dipped galvanized. As suggested, a flap disc works well for prep but watch the fumes. A fan would interfere with a gas shield causing you to turn up shield gas, but galvanized it nasty. Newer vehicles (94 & up) in the GM line has 300 series stainless in front of the cat, 400 behind it because of heat. I would opt for a stick of small size & setting.

Actually this helps me out so much. I'm replacing my exhaust system' though it's direct fit. I feel alone better welding it togethor. Thank you much on the demo 👍
As a professional welder, with a degree in pipe welding, I would suggest using flux core of mig anyway. Exhaust pipe is dirty, and often rusty, and the flux in flux core wire floats those contaminants to the surface. If you tried to use mig wire, you would probably have a lot more porosity, and a shittier weld.
I've got the same welder and it does pretty darn good on exhaust. Its hard to get the welds to look good. I try to run downhill with the gun upside down. Great video, really enjoyed it!
Ive been looking for videos how to weld my pipes. I have a 2000 chevy blazer with the exhaust humped like that in the back and this helped me alot. Thank you!
Well explained, thanks for starting with the safety equipment and prep work. you have exactly the same equipment I do, lol. I got my flux 125 welder with the auto darkening helmet and 10lb spool thrown in on Craigslist for 35 bucks from an old guy who got it from his grandson and just never used it. Great deal :-)
Thanks for this video. I'm going to give it a try with a rental welder. $40 for a 4 hour minimum, comes with the helmet. I'm guessing from the comments that the thing is kinda like a glue gun? Keep the thing moving and then you don't blow thru the pipe?
Also, if you are welding overhead, it's best to have a welding apron so you don't ruin your t-shirt with burn holes (like I've done to several shirts).
Be sure and disconnect your battery when welding on truck you can cook your electronics be careful about wielding close to the fuel tank gas vapor is extremely flammable some guys like to welding with a full tank of fuel less here vapor that way
Im about to do my exhaust pipe changing tomorrow and have the same exact welder . Mind taking a sec to tell me what size/ type wire and what feed setting you had it on your machine, sir? Much appreciated. Never welded before. Im super nervous, just have a estimated set up to start one Thank you x1,000,000 again!
Guess he never told you what settings huh?? Figures, I was wondering the same thing . Not to mention how to weld the pipe, which he never once talks about.
Nice video! If I give a suggestion, when you weld a muffler or anything else on a car, disconnect the negative battery post. You would avoid electrical problems.
Oh and by the way , that copper nozzle is the wrong one to be used with flux core wire. Yes Harbor freight sold them with the wrong one on the gun and they sell flux core nozzles for like 8 bucks but they don't fit the welder. Just ditch the copper nozzle its for Mig(w/ Gas) welding and that's not what you are doing.
Thanx for this tutorial. My converter is bolted to the exhaust manifold. (Factory). Im planning on cutting out cats, and putting in new cats and welding them in. Its a 32 year old northeast car and im thinking why bother try to unbolt flanges or remove exhaust manifold when i know that i couldnt be able to remove them Im thinking first i should use engine degreaser to clean out all fluid leaks that are down there. What other things should i consider to avoid fire? And will a regular cheap flux welder from harbor freight will do the job?
shemail goondall I would recommend cleaning the cat first, lacquer thinner works sometimes. If cleaning is not an option try removing the entire exhaust pipe so you can ensure a good and solid weld. The flux core should be fine; I’ve used mine to weld exhaust pipes, frame repair, weld broken hinges etc and never had issues.
@@PhillipsVision Alrite. I see a welder harbor freight for as low as 100 bucks, and im gonna pickup a a sawzall, grinder, and a another grinder from sandwich shop(probably the most important item), Thanx for the reply Btw, these muffler shops total ripoff. They use universal cheap converters Nd mufflers, Nd they only weld. They charge alot of money to.
One thing I learned to do pretty quickly by watching CZcams videos was to remove that little fake mig nozzle at the tip, it just gets in the way of seeing the weld and there's no gas going through so I don't need it.
What did you use to remove the dirt and rust from the pipes? Sorry I’m just learning how to do this because my stock exhaust on my c4 corvette rusted out I’m looking to replace it but figured I’d try to learn to see if it’s doable first
Any chance u can reply with what u have the flux welder set at? I just picked one up and can’t seem to get everything just right for exhaust pipes/thickness or rather THINness. I either burn through it or can’t get it to puddle at all. Really frustrating lol.
This was filmed a while back so I don’t remember specifics. This welder is a cheap one so if I recall, the temp was just min and max…I had it on max. The speed was around 6 or 7 out of 10
What is exhaust pipe made of? It acts weird when you try and cut it with a cutting torch. It's like you're trying to cut cast iron or something it just turns to goo instead of cutting like regular steel would.
welds to cold lots of stacking and spray , you're to far away from the pipe , lead out an inch inch n half also weld sideways not 90 degrees so you can push back on the puddle and stack dimes . work on the speed and feed its way to fast
The last part we saw where you weld new to old fixed pipe but you did not show the finished weld. From my experience welding in the shop is no big deal, on the other hand laying under the vehicle welding to a fixed old pipe is. You can jack it up and use ramps etc but the top and upper sides present an issue for prep cleaning and welding them with limited access . I believe using a lift so it can be raised higher to stand under the vehicle will eliminate a lot of that but here again not all. If your going to tell it please tell the whole story.
Abel Monreal I wait for it to puddle, and slowly drag the puddle. Keep in mind that I am not a professional welder, just do basic welding for automotive repair.
Thanks for the video.I have a similar situation with an RV I just wanna make sure because the propane and gas.How did you hook your welder up to the vehicle to weld it without risking explosion?
I welded the majority of the exhaust pipe with it off the vehicle. The little part bear the exhaust manifold was rusted on and could not be removed. I welded very carefully, but that is not recommended. It’s always best to remove the pipe from the vehicle
From my lifetime of welding experience . You should always weld pipe all the way around. Never weld on a vehicle with the battery connected or you will fry the wiring and computer. With welding exhaust pipe it is best to tig weld it if you can. If not its best to mig weld it then you have a cleaner weld and it makes everything look a lot better.
Easiest way to get to the top is to use a jack to support the exhaust, then take it off the hangers. It'll give you at least enough room to weld the top. But of course the best method is to completely remove the exhaust so you have as much room as possible.
@@MIKECANADAMUSIC the reason I ask is because on two occasions with 2 different cars I've had the catalytic converter removed and replaced with a straight pipe and the job was done in less than 15 minutes. Hardly enough time to remove the exhaust. And I always didnt think of asking the mechanic until after I had left lol. Thanks for replying!
It was hard since the pipe could not be removed. I had to reach up around it and do the best I could. I had to be very careful since it was near flammable components.
@@PhillipsVision On this 03 Pilot I am working on, I will take some pics and maybe a little video of my solution. I will not know until I get the bits all cut and placed, but I expect a similar process to your solution. Your vid did offer a lot of insight, thank you.

@@garohseven7971 are you trying to learn MIG welding like this, or stick welding or Tig? If you want I can DM you some shots of my textbook with the very basics. If I can find the thing it's been a while since I've seen it
The proper way is to remove the exhaust pipe and weld it all around. This pipe was seized on due to rusted nuts/bolts, otherwise I would have removed it.
Chris fixes all are you using clean metal? If the metal is dirty it may burn away the impurities. If you turn your setting low and properly clean the metal you should be fine
thanks for that im welding some brand new mild steel pipe all prepped up with drill wire brush im making some custom bit of pipe but im only tacking it together for someone else to finish, any hints for quick tacks?
james anderson I don’t know about tack welding with the flux core. I tried that years ago but it didn’t work well. May need a MIG for a good tack weld. What you can do it maybe run a 1/4” strip in three places to hold it.
To be honest I don’t remember, that was filmed a couple years ago. I believe power was max and wire speed was fast. It should have been slower to keep it better.
Chris Saunde not sure. Anytime you’re near flammable liquids I’d be careful. If you’re welding near it I’d remove it, or remove the item that needs to be welded.
TheStranger5250 if you can get the entire pipe off that’s best. With this particular truck the connection of the exhaust pipe and manifold was rusted so the Nuts were seized.
Good question. I chose downhill due to it being quicker, and since the steel was not that thick. For more structural steels I prefer uphill since it is sturdier.
Buritoman401 normally uphill is preferred since it’s stronger, but you can get away with downhill if the steel isn’t that thick. This exhaust pipe was a lot thinner than others I’ve worked on.
Welding mig downhill is common practice it is when you're welding stick that downhill is not advised and uphill is the preferred method due to the way the slag forms
OOF. Them welds are ROUGH. But I guess it got the job done. Does anyone know if a mig welder would be better for exhausts then stick? I have only used stick.
Get Lincoln or Hobard mig with gas capable. If you can afford it, get Miller 220volt, it'll be the last welder you'd buy for diy welding projects. Don't waste your money on cheap flux core only welder like $99 from harbor crap/freight.
You should mention that whenever welding on a vehicle you should disconnect the negative battery cable so you don't fry any of your electronics.
id like to add that if you're welding on older vehicles without CANbus systems (digital) it's ok. But the vehicle has Canbus use a surge protector on the battery instead. It has to potential of burning out modules.

get a better welder with mixed gas, the welds will be much better.

You SHOULD do little circles. It’s really cursive L but C’s work too. If doing overhead turn the wire speed up.
Motion swirling like motion pull or push and watch the puddles

by feel. you start the bead at the highest point and then drag it down on either side. gravity is your friend.
The pipes being joined makes the seal, the weld keeps them from coming loose.

thanks for that im welding some brand new mild steel pipe all prepped up with drill wire brush im making some custom bit of pipe but im only tacking it together for someone else to finish, any hints for quick tacks?
james anderson I don’t know about tack welding with the flux core. I tried that years ago but it didn’t work well. May need a MIG for a good tack weld. What you can do it maybe run a 1/4” strip in three places to hold it.
the wrong setting
what exact model is the welder?
Chicago Electric - 90amp Flux Core Welder. I got it at Harbor Freight a few yrs back for around $125
What settings do you have your welder on?
This was filmed a few years ago, but I believe it was MAX with med speed
What voltage and wire speed were you using?
To be honest I don’t remember, that was filmed a couple years ago. I believe power was max and wire speed was fast. It should have been slower to keep it better.
How did you weld the top of the pipe on the manifold pipe?
I reached around with the gun. The manifold was stuck so I could not remove it.
Did u have the gas tank removed. I heard you shouldnt weld with the tank on the vehicle
Chris Saunde I did not; gas tank is at the other end of the vehicle. I never remove the tank unless I’m welding near it.
@@PhillipsVision thanks . U wouldn't happen to know if it's okay with a plastic tank
Chris Saunde not sure. Anytime you’re near flammable liquids I’d be careful. If you’re welding near it I’d remove it, or remove the item that needs to be welded.
How are you supposed to get all the way around the pipe when it’s on the car. Seems like you wouldn’t be able to get to certain spots.
TheStranger5250 if you can get the entire pipe off that’s best. With this particular truck the connection of the exhaust pipe and manifold was rusted so the Nuts were seized.
@@PhillipsVision That didn't answer the question.
TheStranger5250 it’s hard, and sometimes almost impossible. Best answer your going to get.
Tyler Gaul that’s how you get exhaust leaks though right? Sorry not trying to be a smartass I’m just learning these things as well
Wire feed or stick better?
I personally like wire feed
You have your wire way to far out
Thanks for the feedback 👍
Is it a flux 90 or a flux 125
Jeremiah Renteria it’s an old flux 90
@@PhillipsVision will a flux 125 work as well?
Jeremiah Renteria yeah, and probably better
Great video, whats the welder name u used? U said u got it from harbor freight tools? Please name it so i can buy it
I have a Chicago Electric 90amp welder, the new ones are 125amps
@@PhillipsVision wow thank u for the quick reply, any idea how much? And which wire i should get?
@@dannyg1748 $139.99 and it takes flux core wire. It should come with a roll, but you can purchase more for $19.99 a roll.
@@PhillipsVision sounds good to me, the mask and gloves u got from hft as well? Or for better quality is better somewhere else?
@@dannyg1748 everything was from Harbor Freight
Yea your not soppose to weld stainless steel with flux core
Any reason why you were welding downhill?
Good question. I chose downhill due to it being quicker, and since the steel was not that thick. For more structural steels I prefer uphill since it is sturdier.
Phillips Vision thank you i thought maybe to help with heat or something but that makes sense
Buritoman401 normally uphill is preferred since it’s stronger, but you can get away with downhill if the steel isn’t that thick. This exhaust pipe was a lot thinner than others I’ve worked on.
Welding mig downhill is common practice it is when you're welding stick that downhill is not advised and uphill is the preferred method due to the way the slag forms
I'm not a trained welder, but wouldn't it be the same thing with his wire welder because he was using flux core and no gas?
Bro take a welding class other than that good video.
Ralph Vielma thanks for the feedback
OOF. Them welds are ROUGH. But I guess it got the job done. Does anyone know if a mig welder would be better for exhausts then stick? I have only used stick.
Doesn't matter if they look rough, they are underneath the car!!
Get Lincoln or Hobard mig with gas capable. If you can afford it, get Miller 220volt, it'll be the last welder you'd buy for diy welding projects. Don't waste your money on cheap flux core only welder like $99 from harbor crap/freight.
No catalytic on there??
ypcomchic it was stolen. The owner just needed the pipe welded to eliminate the loud noise until they can buy a new cat
Goddamn that weld was dogshit.
u need to weld some more
yah!
What do you s what you said your welder on to weld pops with what settings
Not sure if I understand your question
What setting did you use on your welder?
Min with a 3 or 4 speed, I think. This was filmed a few years back
I have the same equipment what do u set your welder settings on for exhaust pipe???
Use slow speed and low temp. I used a higher temp in this video, and it was not the best
@@PhillipsVision Oh ok thank you buddy I usually use wire speed at 3 but I'll have to try putting it on min instead of Max
@@PhillipsVision That little welder is great thats for sure can't beat it for the price
@@tncountryboy34 what’s the model?
